IMPROVEMENT IN STEAM-ENGINE CONDENSERS.

Specification {b1-ming part ot' Letters Patent No. 84,773, dated December 8, 1868.

To all whom it may concern:

Be it known that we, JOSEPH SHIRT and CHARLES BRIGGS, both of Tamworth, in the county of Stafford Kingdom of Great Britain and Ireland, have invented certain new and useful Improved Apparatus for Condensing the Steam of High-Pressure Steam-Engines; and we do hereby declare the following to be a full, clear, and exact description of the same, refei ence being had to the accompanying draw-A ing, and to the letters of reference marked thereon.

This invention has for its object improved apparatus for condensing the steam of highpressure steam-engines. For these purposes an air-tight chest or vessel is applied to the exhaust-pipe of a high-pressure steam-engine.' Above the point where the exhaust-pipe is applied to the chest or vessel there is a perforated partit-ion, or other provision is made for dividing` the condensing-water 'into numerous streams. The condensing-water is introduced by a pipe at the upper part of the chest or vessel from a cistern, or otherwise, so as to keep up a constant supply, which may be regulated by a Vcock or valve. From the lower part of the chest or vessel a waste-water pipe descends, and the lower end of such pipe is constantly covered with water in a well or cistern or other vessel. The exhaust-steam flows from the steam-engine into the air-tight chest or vessel, and is there condensed, while the steam in the engine acts on the piston, which, on the other side, is subject to a par-` tial vacuum.

' In order to enable others skilled in the art to make and use our invention, we will now proceed to describe its construction and operation, reference being had to the accompanying drawing, which forms a part of this specication, and in which the gure illustrates a sectional elevation of our improved condenser.

Ais the air-tight chest or vessel; B, eductionpipe from a steam-en gine. C is the water-supply pipe, having -a regulating-cock, D, thereon. E is a perforated plate, by which the water is divided into numerous streams. F F is the Waste-pipe or hydraulic column, communicating with the hot-well G, having an outlet, H. The length of this waste-pipe or hydraulic column F will vary, depending on the situation of the steam-engine, the supply of water, and the extent of vacuum desired. It

is preferred that this column should be aboutv thirty feet in height; but we have derived considerable advantage when using a pipe of much less height.

We are aware that a chest, communicating with a well, the exhaust-pipe of an engine, and with a reservoir of condensing-water, and divided into three compartments, which communicate through pipes provided with valves. has been used, and is described in the patent of G. J. Washburn, December S, 1863; but it will be seen that the parts of our apparatus are arranged differently from, and that the apparatus is less complicated than, that of Washburn.

Without claiming, broadly, the reservoir or case, with its partition and pipes,

We claim as our invention and desire to secure by Letters Patent A condenser constructed and operating as herein described.

In testimony whereof we have signed our names to this speeication in the presence of two subscribing witnesses.
